It doesn't look like he's creating the library, he's creating a link to 
the library in the XvMCConfig file.

On my perfectly working NVidia 6200 based frontend I have the following:

- compile flags: --enable-xvmc --enable-opengl-vsync --disable-xvmc-pro 
--disable-xvmc-vld --disable-xvmcw

- preferred encoder set the same as you

- XvMCConfig contents:

- /etc/X11/XF86Config needs to have the Device section use the "nvidia" 
driver, not the "nv" driver.

There are other things that can be done to optimize XvMC, but that is 
pretty much the bare minimum.


There is other stuff to do to optimize XvMC, but that is the minimum to 
get you going
